Electronic Label Serial Data Interface for Multi-Screen Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic labels face high manufacturing costs and inflexibility in displaying content, particularly in scenarios requiring multiple displays with diverse and dynamic content updates.
Innovation Solution
An electronic label system comprising multiple display screens, a communicator, and a controller with a serial data interface that transmits content data and control signals to control the screens, allowing for flexible display of the same or different content on each screen, reducing the number of interfaces and simplifying data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display screens are used to enhance display flexibility and content diversity, then display adaptability is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple display screens into a single electronic label device, allowing them to be controlled uniformly through shared interfaces. The controller integrates multiple functions to manage all display screens, reducing the need for separate control circuits for each screen and thereby lowering overall device complexity while maintaining display flexibility.
Solution Approach 2:
The patent implements a universal controller that can manage multiple display screens with different content requirements. The controller is designed with multi-functional capabilities to handle various display modes, content types, and update frequencies, enabling a single device to adapt to diverse display needs without requiring specialized hardware for each function.
2Reliability
If traditional data transmission interfaces are used for multiple displays, then data transmission reliability is improved, but manufacturing cost increases
Solution Approach 1:
The patent combines multiple data transmission interfaces into a single integrated interface structure. Instead of providing separate interfaces for each display screen, the system uses shared serial data interfaces that can communicate with multiple screens sequentially, reducing the total number of interfaces required and lowering manufacturing costs while maintaining reliable data transmission.
Solution Approach 2:
The patent employs a copy-based data transmission approach where a single data stream is replicated and distributed to multiple display screens. The controller copies the data from the serial interface and distributes it to the appropriate display screens, ensuring reliable transmission without requiring dedicated interfaces for each screen, thereby reducing manufacturing complexity and cost.
